Whole Grains Help You Live Longer: Harvard Study

By    |   Monday, 05 January 2015 03:57 PM

Eating lots of whole grains can boost your longevity. That’s the upshot of a new study from the Harvard School of Public Health that indicates each average daily serving of whole grains lowers a person's risk of dying from heart disease by 9 percent and lowers the overall risk of dying from anything by 5 percent over a quarter-century.

The benefits probably come from bran, that fibrous coating that processing takes off of whole wheat and brown rice, the researchers write in the American Medical Association's journal JAMA Internal Medicine, NBC News reports.

To reach their conclusions, Harvard researcher Hongyu Wu  and colleagues examined information from two major, long-running public health studies — the Nurses' Health Study, which has tracked more than 74,000 women between 1984 and 2010, and the Health Professionals Follow-Up Study, which monitored nearly 44,000 men from 1986 to 2010.
 
The studies provide a gold mine of information to researchers. The volunteers get regular medical exams and agree to have their medical records open for scrutiny. They also are surveyed about what they eat, how often, if they exercise, smoke, and other personal habits.
 
For the latest study, Wu's team determined that study participants who ate whole grains more regularly were less likely to die, period, during the course of the research and were much less likely to die of heart disease.
 
"Eating whole grains as a regular part of a healthy diet for many years is associated with a lower risk of death from cardiovascular-related diseases," the researchers said.
 
"These findings further support current dietary guidelines that recommend increasing whole grain consumption to facilitate primary and secondary prevention of chronic disease and also provide promising evidence that suggests a diet enriched with whole grains may confer benefits toward extended life expectancy."
 
Whole grains include whole wheat, brown rice, and whole oats.
 
"Replacing one serving of refined grains or total red meat with one serving of whole grains daily was associated with lower cardiovascular disease mortality: 8 percent for replacing refined grains and 20 percent for replacing red meat," the researchers wrote.
